Correct answer: A
Concept
In a computer, processing components either transform data or direct its movement. Primary memory holds working data for immediate CPU access, whereas secondary storage retains data outside primary memory.
A matching question is solved by assigning each component to its defining function and then checking that every description is used exactly once.
Application
Component | Defining function and match |
|---|---|
ALU (A) | Performs arithmetic and logical calculations — II |
Control Unit (B) | Directs input-output flow within the CPU — III |
Pen Drive (C) | Provides removable secondary or offline storage — IV |
Main Memory (D) | Provides immediate access to active data and instructions — I |
Cross-check
A–II, B–I, C–IV, D–III assigns immediate-access storage to the control unit and CPU flow direction to main memory.
A–I, B–III, C–IV, D–II assigns immediate-access storage to the ALU and arithmetic-logical calculation to main memory.
A–IV, B–III, C–II, D–I swaps the roles of the ALU and the pen drive.
Therefore, the complete matching is A–II, B–III, C–IV, D–I.
